Power Management IC Series for Automotive Body Control  
White Backlight LED Driver  
for Medium to Large LCD Panels  
(Switching Regulator Type)  
No.10039EAT07  
BD8119FM-M  
Description  
BD8119FM-M is a white LED driver with the capability of withstanding high input voltage (36V MAX).  
This driver has 4ch constant-current drivers integrated in 1-chip, which each channel can draw up to 150mA max, so that  
high brightness LED driving can be realized.  
Furthermore, a current-mode buck-boost DC/DC controller is also integrated to achieve stable operation against unstable  
car-battery voltage input and also to remove the constraint of the number of LEDs in series connection.  
The brightness can be controlled by either PWM or VDAC techniques.  
Features  
1) Input voltage range is 5.0 to 30 V  
2) Integrated buck-boost current-mode DC/DC controller  
3) Four integrated LED current driver channels (150mA max. each channel)  
4) PWM Light Modulation (Minimum Pulse Width 25µs)  
5) Built-in protection functions (UVLO, OVP, TSD, OCP, SCP)  
6) Abnormal status detection function (OPEN/ SHORT)  
7) HSOP-M28 package  
Applications  
Backlight for car navigation, dashboard panels, etc.
